SPEGIEICATION forming part of Letters Patent No. 224,178, dated February 3, 1880.

' Application filed June 11, 1879.

To all whom it may concern:

Be it known that I, J AooB EDSoN, of Boston, in the county of Sufiolk and State of Massachusetts, have invented certain new and useful Improvements in Hammock-Supports and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, andto letters of reference marked thereon, which form apart of this. specification.

My invention relates to improvements in hammock-supports of that class in which a pair of tripods united by a central brace are used for the suspension of a hammock; and it consists, first, of a pair of tripod-heads, each one having screw-threaded perforations, into which the detachable screw-threaded legs that compose the tripods are screwed, as well as the ends of the screw-threaded central brace, by which arrangement the whole may easily be packed for transportation or otherwise in a very convenient package. All that is needed for this purposeis to unscrew two or more legs from each tripod-head, as well as to unscrew and detach the central brace from the said tripod-heads. Through the lower ends of the tripod-legs are made perforations, one in each leg, into which is inserted a cross-pin or lever, the object of which is twofoldviz., to act as a stop, so as to prevent the legs from penetrating the ground in case the tripods are set on a lawn, beach, or other soft ground; and,

secondly, -to serve as levers or handles to take hold of when it is desired to attach or detach the legs from their screw-threaded heads without the additional use of pipe-wrenches or similar tools.

Jointed to the central brace is the shadeframe, that is covered with a cloth or awning of suitable material, so as to serve as a sun-shade. The said shade-frame is provided in two of its opposite ends with a pairof downward-projectin g brackets, the lower, ends of which are j ointed to the brace that connects the. tripod-heads, by which arrangement the center of gravityof the frame is placed considerably above'the axis around which it turns, so that .by means of suitable cords or links that are attached to the sides of said shade-frame it can easily be tipped to any desired angle, according to the direction of the sunsrays, and when so tipped to either side on its fulcrum it will automatically remain in any desired position by means of one cord or link onlythat is, the cord going from the highest-part of the shade-frame to either of the two central'legs for the tripods, or to any other stationary part of the support, and in this manner, by using one slack cord from each end of the shade-frame to any stationary lower part of the tripod, the said shadeframe may be operated around its fulcrum to the right or left simply by pulling on one or the other of the slack cords, when the frame will remain in the desired position, owing to the increased weight thereof on one side of its line of suspension.

The said shade-frame is loosely jointed to the central brace, so that it can be moved forward and back thereon in the direction of the center line of said brace, according to the direction of the suns rays, which arrangement is very useful, as it enables me to use a considerably-\shorter shade or awning as compared with a rigid shade-frame, and besides cheapening it, without detracting from its value as a sun-shade, it is made more portable, and can be packed in a smaller compass for transportation or otherwise, as may be desired.

I prefer making the central brace in two or i more pieces and screwed into each other or coupled together by suitable screw-couplings, for the purpose of being able to detach it into pieces not exceeding the length of the tripodlegs, so as to pack the whole, when taken apart, in as small a compass as possible.

The upper end of each tripod-head extends upward as a projection, to which the end of the hammockcan easily be attached and supported, if so desired.

On the accompanying drawings, Figure 1 represents a plan view of my invention. Fig. 2 represents a sectional elevation. Fig. 3 represents an end view; and Fig. 4 represents a perspective View.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings. r V

Said brace is preferably made in two or more parts, as hereinbefore described.
